Huawei Sports Bracelet uses the more scientific and professional Huawei TruSleep sleep detection technology, the principle of the monitoring method is the same as that proposed by Harvard Medical School's cardiopulmonary coupling analysis technology, and has passed the certification test of the Harvard Medical School's CDB, which allows you to determine the time and proportion of each sleep stage that occurs, thus accurately portray the sleep structure.
There is also a marvelous coupling between heart rate and respiration when a person is asleep. This coupling is enhanced when a person is asleep. This coupling is also characterized differently in light sleep, rapid eye movement, or some disease states such as sleep apnea.
Based on this discovery, the Harvard Medical School CDB, in 2005, innovatively proposed CardioPulmonaryCoupling, or the concept of cardiopulmonary coupling, or CPC for short, and developed a mature technique that can accurately give sleep staging. These results have been clinically validated to be in good agreement with the results of sleep staging judged by traditional brainwave-based methods.
This analytical method is FDA-approved and can be used as a safe and effective clinical sleep quality assessment tool. A large number of clinical trials in medical institutions in the US, Europe, and Asia (including China) have also proven the accuracy and reliability of CPC technology. Huawei Sports Bracelet is based on this technology, making its sleep monitoring data more accurate.
Expanded Information
Smart sleep monitoring is generally categorized into three types: cell phone APP monitoring, wearable device monitoring, and non-wearable device monitoring.
Mobile phone APP monitoring. Cell phone APP monitoring sleep is to use the acceleration sensor and gyroscope inside the phone to monitor the sleeping action, so as to analyze the sleep quality, deep sleep time and so on. This kind of APP will prompt you to put your phone on the bed in a certain position, and then it will start to record the series of process from lying down to enter sleep to deep sleep to wake up according to the vibration of the bed.
This kind of APP generally says that it has the following functions: monitoring the time of entering sleep, monitoring the time of deep sleep, recording the function of dreaming or snoring, recording the time of wakefulness and so on. But it is not difficult to find out that the cell phone APP monitoring from the principle is through the phone's sensor, to sense the vibration of the bed, which is okay for single people, the bed is only one person.
If it is a husband and wife sleeping together in a double bed, how does this vibration count? And monitoring with a cell phone app, there are also problems with radiation, power consumption and so on. It's even less likely to monitor data like pulse and oxygen saturation for people who aren't in direct contact with the person being monitored.
Wearables. Wearables have their own accelerometer sensors and can record your movements without relying on your phone. Whether you're wearing a bracelet, a watch, or a ring, wearables that fit around your body and move with your body's movements can sense your movements more accurately with built-in accelerometer sensors.
When the accelerometer sensor inside the wearable device records your movement, it can transmit your data to your phone via Bluetooth, and analyze it through the personal data provided by the user, such as age, in the cell phone app, and eventually give a statistic in the app. What data this statistic will all contain depends on what hardware your wearable device has as support.
For example, if your wearable device has a heartbeat heart rate sensor, it can record your heartbeat changes while you sleep. If it has red and infrared LEDs, it can also detect blood oxygen levels. All of these are complementary to your sleep monitoring for analyzing results, and are much more accurate than cell phone monitoring. And wearables are independent and won't be affected by the people they sleep with to monitor data.
This measurement is already much more accurate than a cell phone, but to thoroughly know how your brain waves are active while you sleep, or to accurately analyze what is causing your insomnia, a bracelet is far from being able to do that.
Non-wearable devices. Some of the more common non-wearable devices are smart mattresses, smart pillows, smart bed straps, and smart pillow snaps. This kind of smart hardware products individually designed only for monitoring sleep generally have built-in high-sensitivity sensors, they can record the user's sleep quality, heart rate, breathing and snoring.
Users can view the software-analyzed sleep reports on their phones via a Bluetooth connection. Meanwhile, most smart devices that are not wearable to monitor sleep also have features that can play background music that promotes falling asleep, and smart alarm clocks in the morning to make waking up from a light sleep relatively painless.
The biggest weakness of wearable devices is their inability to record and analyze breathing, which is the strength of non-wearable devices. Non-wearable devices also monitor sleep quality by targeting an individual's movements, and although they are placed on the bed, they are in close proximity to the person, making movement recording more accurate.
But still, this kind of sleep monitoring can only achieve the effect of monitoring, although it can help you analyze the data of deep sleep, breathing, heartbeat, etc., but it can't accurately tell you where the problem of your sleep is. There is still a gap with the real meaning of sleep monitoring in hospitals. Smart wearable devices can monitor sports health, and the common ones are heart rate monitoring, blood oxygen monitoring, sleep monitoring and so on. Apple's watch can also support sleep monitoring, that applewatch how to see deep sleep?
applewatch how to see deep sleep?
1, open the sleep app of AppleWatch or the health APP of your cell phone, and set the sleep goal.
2, wear the watch to sleep, Apple_atch can track to see the deep sleep situation, that is, sleep time. When you wake up, open the Sleep app to see how much sleep you've gotten and to see your sleep trends over the past 14 days.

How do smart wearables monitor sleep quality?
Everyone from going to bed to really fall asleep, the body will always have a variety of changes to the smart watch bracelet, to sleep when they wear them on the wrist, will inevitably produce a variety of displacement with the body's movement changes, gravity point changes, the sleep monitoring function of the smart watch bracelet will be recorded and to determine whether the person is sleeping. Microgram Technology has independently developed a variety of sleep, heart rate, blood pressure, blood sugar and other sub-health function algorithms, users in the use of smart wearable products, smart wearable built-in "sleep" health function algorithms, one can remind the user to go to sleep within the preset time, and the second can track the human body sleep to measure the user's sleep quality, and guide the user to develop a healthy sleep quality, and to guide the user into a healthy lifestyle. The newest addition to the smart wearer's portfolio is a new, more advanced, and more advanced sleep function that allows the user to sleep for a longer period of time.
